"My advice to Sunday schools, no matter what their denomination, is: Hold fast to the Bible as the sheet anchor of your liberties; write its precepts in your hearts, and practice them in your lives.

'Righteousness exalteth a nation; but sin is a reproach to any people.'" - June 6, 1876, in a letter from Washington during his term as President, to the Editor of the Sunday School Times in Philadelphia.
